Uses of E357 (Potassium Adipate)
E357 (Potassium Adipate) is found in Herbal salts. It is metabolised in the body or excreted in the urine.
E357 (Potassium Adipate) is used as a firming and raising agent used in baking powder, beer, all fruit drinks, jams, pudding mixes, ice blocks, margarine, etc.
Also used in the production of plastics including PVC, and also in antacids, which is strange considering it is an acid.
E357 (Potassium Adipate) indications
For the treatment of patients with hypokalemia with or without metabolic alkalosis, in digitalis intoxication, and in patients with hypokalemic familial periodic paralysis.
If hypokalemia is the result of diuretic therapy, consideration should be given to the use of a lower dose of diuretic, which may be sufficient without leading to hypokalemia.
For the prevention of hypokalemia in patients who would be at particular risk if hypokalemia were to develop, eg, digitalized patients or patients with significant cardiac arrhythmias.
The use of potassium salts in patients receiving diuretics for uncomplicated essential hypertension is often unnecessary when such patients have a normal dietary pattern and when low doses of the diuretic are used.
Serum potassium should be checked periodically, however, and if hypokalemia occurs, dietary supplementation with potassium-containing foods may be adequate to control milder cases.
In more severe cases, and if dose adjustment of the diuretic is ineffective or unwarranted, supplementation with potassium salts may be indicated.
Organoleptic Properties: Odor and/or flavor descriptions from others (if found).
